Listing TV’s top shows? Look to cable.

Cable’s top shows continue to stack up well against broadcast at midseason.

Four cable programs placed among the top 15 TV shows in adults 18-49, broadcast or cable, last week, the week ended March 10.

“The Walking Dead” was once again the top show of the week on television, drawing 7.24 million viewers in the demo, according to Nielsen. The 9 p.m. AMC drama topped CBS’s “The Big Bang Theory,” the only other program to draw more than 5 million 18-49s, by 279,000.

Up till this season it was unheard of for a cable show to beat “Idol” in the demo, but a second edition of “Duck” took fifth place, also beating the Thursday and Tuesday “Idols.”

The fourth cable show to place in the top 15 for the week was History’s new series “The Bible,” which averaged 3.166 million in the demo. That was just behind Univision’s “Por Ella Soy Eva” (3.18 million) and ranked 15th for the week, topping broadcast hits “The Amazing Race” (16th with 3.04 million) and “Glee” (17th with 3.08 million).

There certainly have been cable shows that stacked up well against broadcast in the past, such as MTV’s “Jersey Shore” and HBO’s “The Sopranos.”

But the strength of this crop of shows is notable. “Dead” and “Duck” are the highest-rated shows in their networks’ respective history.

“Bible,” though not surpassing the numbers for History’s all-time best program, “Hatfields and McCoys,” isn’t too far behind.

Overall primetime cable viewership among 18-49s is down 3.2 percent during first quarter, according to the TVB, and viewership on the top 10 networks is off even more, 7.2 percent.

So while the big numbers for the series don’t speak to the overall growth of the medium, they do certainly serve as a reminder that the lines between cable and broadcast continue to blur.
